Dell™ worldwide introduction of the next generation PowerVault™ MD3200 and MD3220 External RAID arrays is on June 15, 2010. This document is intended as guidance for a product transition from Dell's MD3000 to the new MD3200 and/or MD3220.

Dell PowerVault MD3200 and MD3220 RAID arrays provide 6Gb/s SAS (SAS 2.0) performance capability and increased flexibility and scalability to the PowerVault array family. These arrays will connect to supported PowerEdge™ servers using the 6Gb SAS HBA.

What’s New?

The PowerVault™ MD3200 and MD3220 series arrays offer the following new features:

2X performance improvements over MD3000

o Up to 2,000MB/s RAID5 sequential reads

o Up to 30K RAID5 random disk reads

Four models to choose from:

o A cost effective, high capacity model (MD3200): Single controller with 2GB of battery backed cache and four 6Gb SAS host ports housed in a 2U, 12 drive 3.5” HDD enclosure. (directly connect up to 4 non –HA servers)

o A highly available, high capacity model (MD3200): Dual active/active controllers with a total of 4GB mirrored battery backed cache and a total of eight 6Gb SAS ports housed in a 2U, 12 drive 3.5” HDD enclosure. (directly connect up to 8 non-HA servers or 4 HA servers)

o A cost effective, high performance model (MD3220): Single controller with 2GB of battery backed cache and four 6Gb SAS host ports housed in a 2U, 24 drive 2.5” HDD enclosure. (directly connect up to 4 non –HA servers)

o A highly available, high performance model (MD3220): Dual active/active controllers with a total of 4GB mirrored battery backed cache and a total of eight 6Gb SAS ports housed in a 2U, 24 drive 2.5” HDD enclosure. (directly connect up to 8 non-HA servers or 4 HA servers)

Support for SAS, near-line SAS and Solid state disk drives

o The ability to mix SAS, near-line SAS and SSD drives within the same enclosure supports a user’s ability to blend drives to best suit their applications’ storage needs across three tiers of performance offerings

Expansion to 96 HDD

o Additional expansion using MD1200 and/or MD1220 6Gb SAS enclosures for a maximum of 96 hard disk drives.

o Enclosures can be mixed behind base models to achieve the highest level of drive tiering

Support for self-encrypting drives (SED) for securing data at rest

Product Positioning

As the next generation of PowerVault non-networked shared storage systems, the MD3200 series replaces the MD3000 in the product portfolio. When looking at Dell’s portfolio of external RAID storage products, the MD3200 series is positioned below the MD3200i series because of its lack of network connectivity and


6

the limited number of hosts supported by the products. Because the MD3200 and MD3200i series of products share a common controller architecture, both products have similar features and functions with the main difference being the number of servers that can connect to the systems and the throughput performance differences resulting from the different host connection technologies. When positioned against Dell’s enclosure portfolio, the MD3200 series of products is positioned above the JBOD offerings because of its ability to offer true high availability with no single point of failure and be shared across a greater number of servers.

The MD3200 series of products is a PowerEdge-centric storage solution that shares common hard disk drives with the servers and capacity expansion via the MD1200 and MD1220 drive enclosures.

Connecting Hosts and Enclosures

Dell™ PowerVault™ MD3200 and MD3220 arrays standardize on the 6Gb/s (SAS 2.0) Mini-SAS cable (SFF 8088). The Mini-SAS cable is unique from the SAS cable used with the previous generation Dell™ PowerVault™ MD3000.

Mini-SAS Cable Transition

Connectors on both ends of the SAS cable are universally keyed. Either end of the cable can be connected to the 6Gb SAS HBA, MD32X0 array or MD1200/MD1220 expansion enclosures.

To remove the SAS cable, pull the pull-tab to release the cable from the SAS connector.

Product Support

Host Bus Adapter (HBA)

The PowerVault™ MD3200 and MD3220 require the 6Gb SAS HBA for server connectivity. The 3Gb SAS 5/E HBA is not support with the MD3200 and MD3220 RAID arrays.

Management Software Support

The Dell™ PowerVault™ MD3200 and MD3220 arrays are managed via the 2nd generation MD Storage Manager software provided on the Resource DVD that shipped with the product. This software is backwards with earlier version of the MD3000 allowing a single pane view to monitor all of your MD External RAID Array systems.

Accessing a MD3200/MD3220 and MD3000 from the Same Server

It is possible to have a single server accessing both an MD3200 and an MD3000 running certain operating systems. The following limitations apply to co-existence.

Requires the MD3000 to be at RC2 firmware version

Requires both arrays to be connected to a 6Gb SAS HBA. (i.e. no mixing of 6Gb SAS HBAs and SAS 5/E HBAs in a server)

Requires the operating system to be support on both platforms

Linux operating systems are limited to the versions of Linux that use Device Mapper (DM) and the multi-pathing driver.

o RHEL 5.4 and 5.5

o SLES 10 SP3 and 11 with update 1.
